MICHAEL FITZGERALD, OF MEDINA, N EW YORK, ASSIGNOR OF ONE-THIRD T0 JAMESH. GONLEY AND ONE-THIRD TO GEORGE R. CONLEY, BOTH 0F MEDINA, NEW YORK.

STREET-INDICATOR.

Application filed February 21, 1917.

To all whom it may con ern:

Be it known that 1, MICHAEL- FITZGERALD, a citizen of the United States,residing at Medina, in the county of Orleans and State of New York, haveinvented new and useful Improvements in Street-Indicators, of which thefollowing is a specification.

This invention comprehends improvements in street indicators, andrelates more particularly to improvements in that type of indicatorsdisclosed in my application, Serial Number 81,940, allowed August 3,1916, and issued as Patent 1,217,737.

One of the objects of the invention is to provide an indicator having aweb movable past a sight opening and carrying the names of streets orstations, means for advancing the web at each operation of the machinesufiiciently far to project a name into registration with the sightopening and to positively lock the web when the name is so positioned.

Another object of the invention is to provide a bell sounding mechanismwhich will operate to sound a bell each time the web is moved todisclose a new name.

The invention also aims to generally refine and improve street andstation indicators to render them more practical, useful andcommercially desirable.

lVith these and other objects in view as will become more apparent asthe description proceeds, the invention consists in certain novelfeatures of construction, com bination and arrangement of parts as willbe hereinafter fully described, illustrated and claimed.

showing the braking means for one of the drum shafts.

Referring in detail to the drawings by numerals, 1 designates, as anentirety, a casing having a front wall 2 formed with a centrallydisposed sight opening 3 and carrying above this opening, a hood orreflector l in which may be positioned a light 5 to illuminate thesignal opposite the sight opening.

Shafts 6 and 7 extend longitudinally through the casing above and belowthe sight opening and carry drums 8 around which a web 9' carryingtransversely disposed and equally spaced indicating names of streets orstations is wound. The shafts extend through the casing wall 10 and eachof them has fixed on its extended portion a ratchet wheel 11. Yokelevers 12 and 13 are loosely mounted on the shafts with their armsextending on opposite sides of the ratchet wheels. These yoke leversconverge rearwardly toward each other and are provided adjacent theiroverlapping ends with longitudinal slots 14 through which a pin 15extends. This pin has an enlarged head movable in the guide 16 andcarries a bail or clevis 17 which is connected to one end of a pull cord18. Springs 19 return the levers to their rear positions after havingbeen actuated by their cord 18. Each of the levers is provided with aspring pressed pawl 20 adapted to engage its ratchet wheel 11. To holdthe pawls from engagement with the ratchet wheels, I provide releasingplates 21 pivotally mounted and each having a marginal recess 22 toreceive the pawl arm 23 and hold the pawl in inoperative position. Thereleasing plates are each provided with a handle 24. which extendslaterally through a slot 25 in the wall 26 of the supplementary casing27.

To stop the web at each operation of the machine after it has moved afixed distance, I provide a stop roller journaled in the sides of thecasing in line with the sight opening. This roller is formed with teethor spurs 29 which work in openings or eyelets 30 formed in theweb'adjacent one edge thereof. The roller is formed with radial sockets31 pref erably four in number to receive a stop means. Mounted upon thewall 10 of'the casing is a pair of ratchet levers 32 which are pivotedintermediate their ends. Each of the ratchet levers is provided on oneend with a tooth 38 adapted to engage a ratchet wheel 34 on thecorresponding drum 8; and on its other end with a tooth or extension 35adapted to seat in one of too sockets a1 and hold the roller againstrotation. in outwardly extending arm 36 is carried by each of the leversadjacent its outer end and extends through an opening 37 in the casingwall. Each of the lovers is normally held out of engagement with theratchet wheels 8% by arr 38 which bears against a collar 39 on the leverarm 36. The angular arms 38 are carried by the yoke levers 12 and whenthe levers are in position shown in rig. they hold the levers 32inoperative against the tension of the springs d0.

To sound bell e1 at each operation of the machine, I provide a lever d2pivotally mounted at its upper end and having an outwardly extending arm43 which extends through the slot eel to strike the bell hammer A spring46 urges the lever 42 toward the bell hammer. A bolt 47 is pivoted tothe lever 42, works through guides 48 and is adapted to project into oneof the sockets 31.

In Fig. 8 is shown the means for braking the drum shafts. 4C9 designatesa bearing having a hollow extension 50 in which is mounted a shoe 51pressed into engagement with the shaft by a spring 52 which bears at itsouter end against a plug 53. This arrangement is provided on one end ofeach of the drum shafts 6 and 7.

In the operation of the indicator, one of the pawls 20 is first thrownout of operation and also the corresponding ratchet lever 82-. Thislatter member is held inoperative by one of the pivoted plates 5% on thesupplementary casing 27, as shown in Fig. 2. New with the partsarranged. as shown, .in the drawings, a pull on the cord 18 will swingthe levers 12 and 13 and rotate the upper drum to wind the web thereon.A the yoke lever 12 moves f rwardly, the arm 38 attached thereto,travels rearwardly allowing the tooth 35 of the upper ratchet lever 32to bear against the periphery of the stop roller 28. When the web hastraveled. sutliciently far to bring one of the sockets 31 in the path ofthe tooth 35, said tooth will seat in the socket and lock the roller,thus stopping the movement of the web. As the tooth 35 snaps into thesocket 81, the tooth 33 on the other end of the lever 32 will engage theratchet wheel 3% of the upperdrum and lock the same, thus completing oneoperation of the device. As the yoke lever 13 moves forwardly, it allowsthe lever 42 to swing rearwardly under the tension of its spring L6 tobring the end of the bolt 4.? against the periphery of the roller 28.lVhen one of the sockets 81 comes into alinement with the bolt, thelatter snaps thereinto, allowing the lever arm 43 to strike the bellhammer a quick blow. When desired, the direction of travel of the webmay be reversed by releasing the lower pawl 20 and lever 32 and lockingthe upper pawl and lever.

From thev foregoing description taken in connection with theaccompanying drawings, it will be apparent that I have provided a very)ractical street indicator having a movable web which is locked againstfurther movement after having traveled a fixed distance on the operationof the machine.

While I have shown and described. thepreferred embodiment of myinvention, it will be cle..., understood, that I do not wish to belimited to this construction, but may make such changes as will fallwithin the scope and spirit of the invention as claimed.
